Abstract 19547: Novel Hemodynamic Subsets in Predicting the Need for Inotropic Support in Heart Failure

Introduction: Forrester hemodynamic subsets, originally applied to acute myocardial infarction, were widely used for clinical assessment and treatment of any types of heart failure (HF). We aimed to elucidate the best hemodynamic parameter to propose novel hemodynamic subsets in predicting the need for inotropic support in patients with chronic HF. Methods: Consecutive 202 patients with HF (66 ± 16 years old, 138 males) underwent right heart catheterization (RHC) before initiation of in-hospital pharmacological therapies for HF within 72 hours after hospital admission between January 2011 and March 2014. Patients who required urgent treatment before RHC were excluded. Left ventricular stroke work index (LVSWI) was estimated by the formula: (mean blood pressure - mean pulmonary capillary wedge pressure (mPCWP)) * stroke volume index * 0.0136 (g/m2/beat). Results: Although 186 patients were successfully treated with diuretics and/or vasodilators, 16 (7.9 %) patients required inotropic support during hospita...
